CRRC Yongji Electric Co., Ltd provides the traction motors for China’s first variable marshalling EMU

raction motors for China’s first variable marshalling EMU

Recently, China's first variable marshalling emu has completed the vehicle commissioning test and passed the unique varible marshalling verification, which is provided with traction power system by the CRRC Yongji Electric Co., Ltd.

The R&D team broke the fixed marshalling mode and redesigned the equipment, functions and structure of EMU. Variable marshalling EMU can calculate the optimal efficiency choice such as the speed levels, number and seat configuration according to the speed and power.

The traction power system of variable marshalling EMU has two kinds of traction auxiliary systems (750KW and 1500KW), including traction transformer, cooling system (water cooling and oil cooling), traction auxiliary converter and traction electric unit.

The variable marshalling EMU could flexibly deal with the fluctuation of passenger flow and passenger demand. In areas with large passenger flow, double-deck, long-marshalling and large-capacity emu trains can be used; In economically developed areas, short marshalling trains with comfortable and large space can be used. Short marshalling trains can be used in areas with low passenger flow. The performance and practicality of variable marshalling EMU have been significantly improved to meet people's yearning for a better travel life.
